College

Carr enrolled as an early-entry freshman for the spring semester at Fresno State in 2009 so he could participate in spring football with the Bulldogs. Then-Fresno State head coach Pat Hill stated that Carr, a true freshman, was "in the mix" for the starting quarterback position as late as mid-July. However, days before the 2009 season began in September, Hill announced junior Ryan Colburn would start over Carr.

After redshirting his 2010 season, Carr took over the starting QB position for Fresno State in the fall of 2011. During his three years as a starter, he threw for 12,843 passing yards and 113 touchdowns.

He wore number 4 as an homage to his favorite NFL player, Brett Favre.

Carr received the 2013 CFPA Elite QB Award for his performance over three seasons at Fresno State. He joined fellow Bakersfield native Phillip Thomas as the school's second CFPA winner.

In 2013, Carr won the Sammy Baugh Trophy which is awarded annually to the nation's top collegiate passer. He joined Trent Dilfer and David Carr as the only other Fresno State quarterbacks to win the trophy. He finished 8th Place in Heisman Trophy voting.
